Scientific Processes

Repetition in an investigation makes the data

• accurate

• replicated

• science-y

• in a graph

Which group in an experiment is not tested?

• experimental

• control

• variable

• data

When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer?

• Dependent
• Independent
• Control
• Compound

What would the INDEPENDENT variable be in an experiment testing which types of paper airplane goes furthest?

• the paper used
• the type of paper airplane
• the distance of each plane's flight
• how hard the plane is thrown

This part of the experiment serves as a basis of comparison:

• control group

• Independent variable

• dependent variable

• data

The summary at the end of an experiment that explains the results.

• conclusion

• hypothesis

• procedure

• question

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what are the controlled variables?

• type of plant, amount of music, and sunlight

• plant growth

• water, apple juice, milk

What is the best example of a hypothesis?

• Do hamsters live longer than rats?
• I think dogs make the best pets. 
• Cars and trucks use the same gas usually.
• Brand B lightbulb will burn longer in a lamp than Brand A. 

A possible explanation to a question based on what is known and observed. The explanation MUST be testable.

• Scientific Method
• Hypothesis
• Observation
• Inference

A scientific test completed to make a discovery, check a hypothesis, or demonstrate something is called _______________.

• an experiment

• research

• a conclusion

• analysis
